Abstract

The embodiment of the present application relates to a method for activating and deactivating a secondary cell and a terminal device. The method includes that the terminal device receives first indication information at a first start time that is sent by a network device to instruct the terminal device to activate or deactivate the secondary cell of the terminal device; the terminal device receives, at a second start time later than the first start time, second indication information that is sent by the network device to instruct the terminal device to activate or deactivate the secondary cell, wherein the terminal device does not activate or deactivate the secondary cell according to the first indication information at the second start time; the terminal device determines, according to apreset rule, that the secondary cell is activated or deactivated according to the first indication information or the second indication information after the second start time. The method for activating and deactivating a secondary cell and the terminal device in the embodiment of the present application can determine to perform activation or deactivation of the secondary cell in case of indication information conflict.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method for activating and deactivating a secondary cell and a terminal device. Background technique [0002] According to the long term evolution (LTE) protocol, the terminal device receives a medium access control element (MAC control element, MAC CE) sent by the network device, and the MAC CE can be used to indicate activation or deactivation of the terminal device Secondary cell (SCell), the terminal device can activate or deactivate the corresponding SCell according to the MAC CE. [0003] In a new radio (new radio, NR) system, the terminal device may also receive downlink control information (downlink control information, DCI) sent by the network device, and the DCI may also instruct the terminal device to activate or deactivate the SCell. Therefore, when the terminal device receives the MAC CE and DCI, especially when the MAC CE and DCI indications are different, ...
